windows 7 starter aero glass?

Hi. ) I just wanna' know if there's a similar software like WinAero's Aero Patch. I was about to install Aero Patch 1.4 but I saw a warning that says your Windows will not be genuine anymore once you install the software. So if there's an alternative software that won't affect your Windows System, kindly please give me it's name Thank you. If there isn't any, it's alright! Thanks!!
